? 2022 Elsevier LtdFor the problem that the flow of fluid around the tuning fork affects the detection accuracy of tuning fork sensor, the current methods to evaluate and reduce this influence still rely on manual experience. To improve the detection accuracy of tuning fork densitometer (TFD), we reported a comprehensive evaluation index (CEI) of fluid velocity to analyze the influence of fluid state on the TFD detection accuracy. In this work, several TFD detectors with specific structures were designed to explore the influence of fluid velocity on TFD. Firstly, the Fluent was used to complete numerical simulation, and the CEI was used to analyze the results. Secondly, an experimental platform was built to collect and analyze the TFD output frequency. Finally, it showed that the evaluation results of CEI were consistent with the experimental results. This research can improve the working stability of TFD in the detection process to a certain extent.
